'7 Claims. (01. 312-51) This invention relates to a novel dispenser forholding a plurality of cloth pads or the like and more especially filterpads and provided with dispensing mechanism for dispensing the pads oneby one.

More particularly, it is an aim of the present invention to provide anovel container for holding a stack of pads and having manuallyoperative dispensing means for extracting the bottommost pad from thecontainer. I

A further object of the invention is to provide a novel means ofextremely simple construction for performing the dispensing operationwhen a hinged bottom portion of the container is swung downwardly andtoward an open position.

Another and important object of the invention is to provide a quickdemountable bracket support for the container to enable the container tobe readily demounted from the support for refilling the container and bereadily repositioned on the support and in substantially an uprightposition.

Still a further object of the invention is to provide a dispenser havinga novel pivoted hook structure for engaging and extracting a filtercloth or pad from the bottom of the stack contained in the receptacle.

Still another object of the invention is to provide a receptacle havingnovel means to maintain the pads or filter cloths in a dry conditionwhen the exterior of the container or receptacle is rendered moist bysweating or humidity.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawing, illustrating a presently preferred embodiment thereof, and,wherein:

Figure l is a bottom plan View of the receptacle and dispenser;

Figure 2 is a fragmentary vertical sectional view thereof takensubstantially along a plane as indicated by the line 2-4. of Figure 1;

Figure 3 is a front elevational view of the bottom section of thereceptacle supporting bracket and with the receptacle removed therefrom;

Figure 4 is a horizontal sectional view thereof taken substantiallyalong a plane as indicated by the line 4-4 of Figure 3;

Figure 5 is a fragmentary sectional view showing afabric pad or filtercloth engaged by the hook structure of the dispensing apparatus and asit will appear while being removed from the bottom portion of thereceptacle, and

Figure 6 is a fragmentary vertical sectional 2 view taken substantiallyalong a plane as indicated by the line 66 of Figure 1.

Referring more specifically to the drawing, the cloth dispenser in itsentirety and comprising the invention is designated generally I andincludes a container or receptacle, designated generally 8, a dispensingapparatus, designated generally 9 and constituting a swingably mountedpart of the bottom of the container 8 and a mounting bracket I0 for thecontainer 8.

The cloth or pad dispenser 1 has been illustrated in the drawing andwill be described in connection with conventional fabric pads or filtercloths such as are employed in stables for filtering milk being pouredinto cans, not shown, in which the milk is transported to dairies. Suchfilter cloths or pads, a plurality of which are illustrated in Figure 2and each designated generally ll, ordinarily include a multiplicity ofplies including a number of upper plies of cotton I2 and a bottom ply ofan open mesh fabric 13 such as cheesecloth. As said filter cloths orpads II are generally disk-shaped to fit the bottom of a milk strainerfor filtering the milk as it is poured into the milk can, the cloths orpads ll have been so illustrated in the drawing and the container orreceptacle 8 has been illustrated as being circular in cross section;however, as the description proceeds it will be readily apparent thatthe pads or cloths l I could be of various shapes and that the container8 could be of various shapes in cross. section to accommodate it to theshape of the cloths or pads. It will also become apparent as thedescription proceeds that the container and dispenser unit 1 couldequally well be employed for holding other pieces of fabric to bedispensed singularly from the bottom thereof.

As previously stated, the receptable or container 8 is shown providedwith a cylindrical wall l4 having an upper edge turned inwardly and backupon itself to provide an internal bead l5 and a lower edge which islikewise turned inwardly and back upon itself but which has the turnedback portion inwardly spaced to provide an upwardly opening channel [6for receiving the depending annular flange ll of a ring, designatedgenerally 18 which is supported therein and which likewise includes anannular inwardly extending flange I9 which forms a part of the bottom ofthe container 8 and which provides a relatively large opening in thebottom portion of said container. As previously stated, the filtercloths or pads ll are stacked in the container 8 and are applied theretothrough the 3 open top thereof and will be supported therein byengagement of the outer part of the lowermost pad II on the inwardlyextending annular flange or bottom portion I 9.

As seen in Figure 2, a portion of the channel I 6 is cut away asindicated at 29 to accommodate a portion of a bar 2| which is fastenedto a portion of the depending flange I! by a rivet or other fastening 22which also extends through the cylindrical wall I4. The bar 2| has aninturned portion fastened to the underside of a portion of the inwardlyextending flange I9 by another rivet or fastening 23.

stricted downturned rolled portion forming a hinged barrel 24 whichforms one leaf of a hinge, designated generally 25- and whichalsoincludes a leaf 2%; having spaced barrels 21 between which the hingedbarrel 24- is disposed and which barrels accommodate a hinge pin 28. Theleaf 2B: is-sec'ured to the underside of a disk 29 by a fastening 39-;said disk 29 being of a size to completely cover the opening in thebottom of the container 8 as defined by the annular flange l9 and havingits outer portion normally disposed against the underside of said flangel9.

An elongated strip 3|, preferably formed of a relatively resilientmetal, is secured to the under side of the disk 29 by a rivet or otherfastening 3| a at a point remote to the hinge leaf 26 and substantiallyin diametrical alignment therewith. The strip 3| is provided with anelongated free end portion which extends outwardly with respect to theperiphery of the disk 29 and which is provided with a downwardly offsetportion 32 which extends around a portion of the channel IS, an upwardlyextending portion 33 which is disposed externally of a part of thecylindrical wall l4 and an outwardly and downwardly curved terminalportion forming a handle 34. A rivet 35 connects a portion of the wall Mto a portion of the flange l1 and has a headed outer end which isengaged by an outwardly bowed part of the portion 33 to combinetherewith to form a spring latch for releasably retaining the disk 29against the underside of the flange I9, as illustrated in Figure 2 andit will be readily ap-' parent that the handle 34 can be grasped andpulled outwardly to disengage the portion 33 from the rivet head and sothat the disk 29 can be swung downwardly with respect to the bottom ofthe container 3 to and beyond its dotted line position of Figure 2. Itwill likewise be readily apparent that the handle 34 can be grasped forreturning the disk or hinged bottom 29 to its full line position ofFigure 2 and that the portion 33 as it reaches its position of Figure 2will snap into engagement with the rivet head for automatically latchingsaid disk or bottom 29 in a position for closin the open bottom of thecontainer 8.

As best illustrated in Figure 1, the disk 29 is provided with anelongated opening 36 which is disposed in alignment with the hinge leaf26 and strip 30. The opposite, inner end of the strip 30 is bifurcatedand the furcations thereof are turned to provide aligned, spaced hingebarrels 31 which are disposed beneath one end of the opening 36. Anelongated plate or strip 38 is disposed normally against a portion ofthe upper surface of the disk 29 over a portion of the opening 38 and ispreferably of a width greater than the width of said opening. Said plate38 has a restricted extension or shank 39 at one end thereof whichextends downwardly Said last men-- tioned portion of the bar 2|terminates in a re wardly extending portions 54 of said arms.

through the opening 33 and which terminates in a hinge barrel 49, asbest seen in Figure 1, which is disposed between the barrel portions 31for receiving a hinge pin 4|. The opposite end of the plate 38, whichextends in a direction toward the hinge 25 is notched to provide aplurality of laterally spaced tapered prongs 42 which are curvedupwardly and backwardly and which combine to form a multi-pronged hookor claw.

Said plate'or strip 38, adjacent the end thereof from which the shank 39projects, is provided with two longitudinally spaced openings 43 whichare loosely engaged by an eye or loop 44 formed on one end of a rod 45which end extends'out'wardly and upwardly through the opening 36. Saidrod 45 is provided with a laterally turned opposite end 46 which isjournaled in a sleeve 41 formed by looping the depending, firstmentioned end of the strip 2|.

The container or receptacle- 8- is adapted to be' demountably supportedin an upright position ona vertical wall surface 48- and which isaccomplished by the bracket I9 which includes a bottom bracket section,designated generally 49 and a topbracket section, designated generally59. Thebracket section 49-, as best illustrated in Figures 3 and 4,includes a plate'which is secured by fastenings 5| to the surface 48 andwhich is provided with laterally spaced corresponding supporting arms 52which form integral' portions of the plate and which extend outwardlytherefrom in a direction away from the wall 43 and which have upwardlyextending outwardly ofiset' portions which terminate in outturnedshoulders 53. The arms 52 are spaced a sufiicient distance apart tostraddle the downwardly extending portion of the strip 2| and portionsof channel l6 rest on the lower out- The upwardly extending portions ofthe arms 52 engage the inner side of the channel H5 and the shoulders53- thereof bear against portions of the underside of the flange IS. Theupper bracket 59 comprises a plate having a lower portion which isdisposed against the wall surface 48 and secured thereto by fastenings55. Said plate is provided with an outwardly offset intermediate portion56 which engages against a portion of the outer side of the cylinder |4adjacent its upper edge and which is bowed to fit substantially fiushthereagainst and has an inwardly extending upper edge portion 57 whichoverlies a portion of the bead l5 and which extends inwardly withrespect thereto.

The receptacle or container 8 is provided with a flanged closure 58 forthe open top thereof and which is provided with an outwardly offsetperipheral portion 59 which fits around the outer side of the plateportion 56 to retain the receptacle 8' in engagement with the upperbracket section 50 when the cover 58 is applied and which likewisefunctions to retain the receptacle in engagement with the lower bracketsection 49.

It will be readily apparent that the receptacle 8 can be refilledconveniently by removing it from its position on the upright surface 48and which is accomplished by removing the cover 58 after which thereceptacle 8 can be swung outwardly and downwardly away from the bracketsection 50 and thereafter lifted off of the bracket section 49. Afterrefilling the container 8 the aforementioned operation is reversed forreapplying the receptacle to the supporting bracket l9 and saidreceptacle is detachably secured in position thereon by the finaloperation of reapplying the cover 58, as previously described.

It will be readily apparent that when one or more of the filter clothsor pads II are contained in the receptacle 8, as illustrated in Figure2, that the bottommost filter cloth or pad may be extracted from theopening defined by the flange [9 by grasping the handle 34 to swing thedisk or bottom 29 downwardly on the hinge 25, as previously described.When this occurs, and as illustrated in Figure 2, the rod 45 willprevent the plate 38 from swinging downwardly with the disk 28 duringits initial movement and instead will cause the plate 38 to assume itsdotted line position of Figure 2 and to continue to swin in a clockwisedirection relatively to the pivot pin 4| so that the prongs or claw 42which engages the bottommost pad H to extract said pad downwardlythrough the opening defined by the flange l9 and will move said padoutwardly with respect to the receptacle 8 or in a direction from leftto right of Figure 2. It will thus be readily apparent that thedispensing apparatus 9 will function each time that the disk or bottom29 is swung downwardly from its full line position of Figure 2 toextract the bottommost cloth or pad I I from the receptacle 8 anddeliver it outwardly so that it can be readily grasped. As the bottom 29is returned to its normal, closed full line position of Figure 2 theprongs or claw 42 will penetrate the next pad or cloth which is thendisposed in a bottommost position preparatory to extracting said pad thenext time that the bottom is swung downwardly.

The annular portion of the container 8 disposed below the level of theflange l9 will function in combination with the cover 58 to keep thepads or cloths H in a dry and sanitary condition and to prevent moisturecaused by humidity within a barn or stable and which collect on theexterior of the receptacle 8 from reaching the pads ll.
